Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 76,254,137, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 76,254,137 | |
| -1 | -76,254,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,254,137.
Example:
1 x 76,254,137 = 76,254,137
and
-1 x -76,254,137 = 76,254,137
Notice both answers equal 76,254,137
With that explanation out of the way, let's continue. Next, we take the number 76,254,137 and divide it by 2:
76,254,137 ÷ 2 = 38,127,068.5
If the quotient is a whole number, then 2 and 38,127,068.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 76,254,137 | |
| -1 | -76,254,137 |
Now, we try dividing 76,254,137 by 3:
76,254,137 ÷ 3 = 25,418,045.6667
If the quotient is a whole number, then 3 and 25,418,045.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 76,254,137 | |
| -1 | -76,254,137 |
Let's try dividing by 4:
76,254,137 ÷ 4 = 19,063,534.25
If the quotient is a whole number, then 4 and 19,063,534.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 76,254,137 | |
| -1 | 76,254,137 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 59 | 1,087 | 1,189 | 1,711 | 2,419 | 31,523 | 44,567 | 64,133 | 70,151 | 1,292,443 | 1,859,857 | 2,629,453 | 76,254,137 |
| -1 | -29 | -41 | -59 | -1,087 | -1,189 | -1,711 | -2,419 | -31,523 | -44,567 | -64,133 | -70,151 | -1,292,443 | -1,859,857 | -2,629,453 | -76,254,137 |
